目的：探讨动态血压监测对老年原发性高血压并心血管事件的影响。方法：将2011．1－2013．1收治的老年原发性高血压300例按白昼舒张压（DBP）分为低舒张压组（DBP＜85mmHg，n＝94）、中舒张压组（85 mmHg≤DBP≤95 mmHg，n＝118）和高舒张压组（DBP ＞95 mmHg，n＝88），随访2年，将随访期间发生心血管事件者为事件组（n＝58），其余为非事件组（n＝242）。结果：与非事件组相比较，事件组的白昼与夜间SBP、DBP 均明显高于非事件组（P ＜0．05），而24 h 血压水平变化率无明显差异（P ＞0．05）；低、中、高舒张压组的心血管事件发生率随着舒张压的升高而明显增高（P ＜0．05）。结论：动态血压监测显示血压高尤其是舒张压高的老年高血压患者更易发生心血管事件，预后差，需严格控制血压。“,”Objective:To explore the effect of ambulatory blood pressure monitoring in elderly patients with primary hypertension complicated with cardiovascular events. Method:300 elderly patients with primary hypertension were divided into low-level DBP group (DBP 9 5mmHg,n=88) according to the levels of DBP from Jan 2011 to Jan 2013.The cases were followed up two years and the cardiovascular events were analyzed. During the period , the patients with cardiovascular events were classified as event group (n=58)and non-event group (n=242). Results:Compared with non-event group, the levels of SBP and DBP at night and day were significantly higher (P 0.05). The incidences of cardiovascular events were increased with higher DBP levels (P < 0.05). Conclusions: For elderly patients with primary hypertension , the higher levels of ambulatory blood pressure monitoring are easier to cause the cardiovascular events with poor prognosis and must control the blood pressure strictly.
